1Neurons are classified in several different ways. From the following statements, select which ones are true.
The two structural classifications are projection neurons and local inter-neurons.
Function classifications are made up of two subcategories: excitatory and inhibitory.
Histological classification includes bipolar, unipolar, and multipolar.
Classifications using a combination of structural, functional, and neurotransmitter type provide the most robust and useful description.
Classification by neurotransmitter type alone provides the most useful description.
A. I only
B. III only
C. I, II, and V only
D. I, II, III, IV, and V
E. I, III, and IV
Answer:
The correct answer is option D. I, II, III, IV, and V
Explanation:
Neurons are the nerve cells that transmit the information in the form of nerve impulses throughout the body. Neurons are an important part of the body and nervous system as neurons control the movement, any other functions of the body. Classification of neurons is presented on different ways such as structural basis, on the basis of functions, histologically, or on the basis of neurotransmitters used by neurons.
Histological classification - bipolar, unipolar, and multipolar.
Function classifications - excitatory and inhibitory.
structural classification - projection neurons and local interneurons.
All type of classification together makes a robust and very useful description of the neurons.

A section of one DNA strand has the sequence ACC GAG GTT. What is the sequence of the strand it binds to?
Answer:
UGGCUCCAA
Explanation:
Basically when you transcribe DNA into mRNA, you find the complementing base pair, for example if G is written in the DNA, the mRNA would show C, and if an A was in the DNA, a U would be shown. It is NOT THYMINE in RNA!! This changes to Uracil in RNA, and that is VERY important. The reason why it is flipped is because of the tRNA. So 3 mRNA nucleotides make a codon, and the tRNA are also in sets of 3, but are called anticodons. The tRNA is complementary to the mRNA strand, AKA the same as the DNA strand except with Uracil instead of Thymine. This is because Thymine breaks down in the presence of Oxygen and so is replaced by Uracil.

What happens when a cell becomes too large? List two possibilities.
Answer: As a cell grows bigger its internal volume enlarges and the cell membrane expands the volume increases more rapidly than does the surface area and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
Explanation:

How does heart rate affect blood pressure
Answer:
Does heart rate affect blood pressure?
A rising heart rate does not cause your blood pressure to increase at the same rate. Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily. When you exercise, your heart speeds up so more blood can reach your muscles.
Explanation:
Answer: As your heart beats faster, healthy blood vessels will expand in size to allow increased blood flow, which helps your blood pressure remain relatively stable.
Explanation: I learned this in science

You're with a team of conservationists who've been assigned to control the marsh mosquito. You can't use chemicals that might harm the valuable organisms that aboung in salt marshes. Plan a strategy that will limit mosquitos without endangering the marsh ecosystem.
I would make a spray that is not harmful to the environment, but instead it kills mosquitoes. If any other animals eats this, they will not die. It is for mosquitoes specificly.

D) by lowering their metabolic rates so drastically that their bodies require a
(Q002) Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living non primate animal that is also a biped. Then, compare its bipedalism with our bipedalism. Try to consider how it moves and some of its possible adaptations (such as limb length). Use resources in your classroom, credible online sources, or books to help you if necessary.
Answer:
One good example of a living non-primate that is also a biped is a Kangaroo. With so much power in their legs and vertebral column like humans, kangaroos are biped, but they leap rather than walk. Their legs are usually bigger than their arms, which enables them to push their whole body off the ground.
However, kangaroos are not just bipedal or quadrupedal but they are both. They also hop bipedally like rodents and many birds, with some displaying skipping gaiety. In addition, chimpanzees, gorillas, gibbons, macaques, capuchins, birds, many lizards, and (at their highest speeds) cockroaches run bipedally.
Explanation:
Bipedalism is the use of two feet for standing and walking. Nearly all primates are capable of bipedalism, although most of the primates spend their time on all fours. Primates are known to move bipedally, but they also use bipedalism to stand up on their hind legs to reach food, look for predators, and for social display and communication.
Discuss the roles of the enzymes secreted by the pancreas during digestion.
Which of the following correctly summarizes the development of the fetus during the second trimester?
Body functions, reflex development, and skin details
Cell division and tissue specialization
Gastrulation, neurulation, and rhythmic breathing
Specialization, function, and growth
Answer:
Body functions, reflex development, and skin details
Explanation:
The second trimester marks the period between the thirteenth to the twenty-sixth week. During this period of fetal development, the fetus begins reflex development such as sucking and swallowing. He is also now able to respond to stimuli.
Body functions are also developing at this stage. The baby can now kick, turn, and move his body. The brains are developing, the hairs and fingernails are also beginning to develop.
Skin details are also developed at this stage. For example, the vernix caseosa is produced to protect the skin of the fetus.

How does competition limit the dispersal of organisms? *
Answer:
Three factors that limit dispersal of a species are physical barriers, competition, and climate. Physical Barriers include water, mountains, deserts, and canyons because these barriers are hard for most organisms to cross, they limit the movement of organisms.
If an animal has to pass through another animals territory to disperse, that animal may be killed or injured in the process, so it may opt not to move or not to move as far as it should.
Explanation:
What type of speciation results in hybrids of the 2 species?
Answer:
Alloploidy results when two species mate to produce viable offspring. In the example shown, a normal gamete from one species fuses with a polyploidy gamete from another. Two matings are necessary to produce viable offspring. The cultivated forms of wheat, cotton, and tobacco plants are all allopolyploids.
Explanation:
what is the steps of the digestion of protein
Answer:
Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.
Hope this helps :)
